迭代法阈值分割，迭代法自动计算最优阈值。已经写成函数形式，输入灰度图，输出分割好后的阈值图。(Threshold segmentation iterative method, iterative method for automatically calculating the optimal threshold. Function has been written in the form of input grayscale output partition threshold after a good map.)

把图像从RGB格式转换到YUV格式的一个函数，直接调用，管他有没有，上传了再说(Image conversion from RGB format to YUV format of a function, a direct call, though he did not upload to say)

说明：  基于matlab的图像处理，裂纹检测算法，非常适合初学者学习(Image processing and crack detection algorithm based on MATLAB are very suitable for beginners to learn)

混合高斯分布EM算法，可以算混合高斯分布的三个参数。混合高斯分布更接近系数分布。(mixed Gaussian distribution EM algorithm can calculate mixed Gaussian distribution of the three parameters. Mixed closer to the Gaussian distribution coefficient.)

自己编写的图像处理函数，包括绘制直方图，直方图规定化，直方图均衡化，具体算法参阅章章毓晋. 图像工程（上册）——图像处理（第二版）[M]. 清华大学出版社(Write your own image processing functions, including the plot histogram, histogram specification, histogram equalization, the specific algorithm see chapter Yu-Jin. Image Engineering (on)- Image Processing (Second Edition) [M]. Qinghua University Publishing society)

RS攻击M程序,用于检测图像是否经过LSB密写(RS attack M procedures for detecting whether the image after LSB steganalysis)

半自动分割彩色图像的颜色相同区域，可以达到PS的魔棒效果(Semi-automatic segmentation of color images the same color region can reach the magic wand effect of PS)

基于MATLAB-GUI图形界面的数字图像处理软件 本系统设计基于GUI图形界面，用matlab语言编写代码，实现功能包括图象的读取、存储、显示、直方图均衡化、阈值化、小波分解、小波重构、加噪、去噪、平滑、锐化、边缘检测、图像分割等(MATLAB-GUI graphical user interface based on digital image processing software of the system design is based on GUI graphical interface, using matlab language to write code to achieve functionality, including image reading, storage, display, histogram equalization, thresholding, wavelet decomposition, wavelet reconstruction, add noise, denoising, smoothing, sharpening, edge detection, image segmentation, etc.)

说明：  1.6尺度不变特征提取，内附代码和文件说明，实证可用(1.6 Scale invariant feature extraction, enclosed code and document description, the empirical results are available.)

偏微分方程图像复原代码，其中有频域迭代盲解卷积H1模型，TV去噪模型，自己编的自适应去噪模型，以及改进的自适应去噪模型，令附卫星图片，PSNR代码(Image restoration code of partial differential equations, including iterative frequency-domain blind deconvolution H1 model, TV denoising model, made themselves adaptive denoising model, and improved adaptive denoising model, so attached to satellite images, PSNR code)
